摘要 |
A primer composition for metallic material comprising (a) a urethane epoxy ester resin having primary hydroxyl groups and a number average molecular weight of 6000 to 12,000, (b) a chromate anticorrosive pigment and (c) a polyethylene wax having a density of 0.94 or more, a molecular weight of 1000 to 10,000 and an acid value of 15 or less (KOH mg/g), the pigment volume concentration being 24 to 45% of the total solids of the composition. A chemical pretreatment on various metallic materials for improvements in scratch resistance, corrosion resistance and the like can be obviated by the use of said primer composition.
